Most of the time, one or more of the resident experts is able to suggest a project setting that takes care of the problem. I am very grateful to you people. But I would also like to know how you came to be so knowledgeable. I don't like to be so helpless, but the only project I have been able to bring forward to BDS2006 is a DLL written in portable Standard C++. Oh, yeah, and some demos from "Beginning OpenGL Game Programming". What I don't understand about the effects of changing project options from defaults would fill volumes. It isn't that I'm a newbie-- I have been successfully building complex Win32 apps with C++ Builder (versions 3 and 6) for ten years. But I'll be hanged if I can figure out what I am doing wrong when I try to bring my current VCL project forward. What would probably help me the most is a roadmap-- something that shows a screenshot of the project settings under BCB6, and then a "where to find it in BDS2006" guide. (Yes, I really am this lame.) Has anybody published an upgrade primer? Thank you for your help.

(Yes, I really am this lame.) There is a find button (top right in the option dialog) which can help you locate a specific option. Quite useful. /Palle Back to top Kathleen Beaumont Guest Posted: Sun May 13, 2007 10:05 pm    Post subject: Re: Desperately seeking BCB6->BDS2006 Update Primer Palle Meinert wrote: Quote: There is a find button (top right in the option dialog) which can help you locate a specific option. Quite useful. Thank you, Palle. That button is useful. But... I have a tiny test application that reproduces a problem I am having with a large project. I prepared a version in BCB6, and then prepared it again for BDS2006. It is a simple form with a button click event handler that makes a call into a 3P library (Codebase by Sequiter) to open and close a DBF table. It builds and runs, but the BDS version throws an access violation on the very first line of code that interacts with Codebase. I also tried letting BDS upgrade the BCB app to BDS. Same result... builds and runs, but throws the access violation. I am comparing command lines between the two versions, and there are differences: The BDS command line does not display -a8 (alignment) or -b (treat enums as ints, which, by the bye, is explicitly required for Codebase). My options PAGES in BDS show "8 byte data alignment", and "Enums always integer sized". Otherwise, and I say this with some hesitation, the command lines appear to agree. This is not an easy comparison to make, because the options are not in the same order between the two compilers. Still desperate, Kathleen Back to top Palle Meinert Guest Posted: Mon May 14, 2007 1:47 am    Post subject: Re: Desperately seeking BCB6->BDS2006 Update Primer Quote: I have a tiny test application that reproduces a problem I am having with a large project.

I just wonder if it is an dll where you could create a new lib with implib? /Palle Back to top danzer Guest Posted: Mon May 14, 2007 9:56 pm    Post subject: Re: Desperately seeking BCB6->BDS2006 Update Primer Quote: I have a tiny test application that reproduces a problem I am having with a large project.

If you are, this will not work. The components must be rebuilt with BDS2006.

I am going to try rebuilding that library under BDS2006 to see if that makes a difference. (I'm sure everybody wishes me luck just so I'll stop posting messages about this!)

Thanks for your input, Kathleen Have you tried using something like madExcept or EurekaLog with your application to help track down the AV?

Danzer I know what line of code is throwing the AV, and am working with the vendor on it. However, I am interested to know what madExcept and EurekaLog are. Will Google for info about them, but if you have some special information, I would be glad to know about it.

I'll try to get the boss to buy a site license for EurekaLog. (But if he can't, I'll at least get one for me.)
